以变量作为条件的 if 语句，该变量可以有多种可能性

Question

print("Welcome to your phones Troubleshooter")
issue = input(str("Does your phone have an issue?"))
if [issue == "yes", "Yes", "YES"]:

我已经为三个选项设置了参数 yes，但它似乎不起作用，它只是继续转到我的 else 语句。 我该怎么办？

Answer 1

你可以

这样做：

print("Welcome to your phones Troubleshooter")
issue = input(str("Does your phone have an issue?"))
if issue.lower() == "yes":
  print("There is an issue")   

或者代码的 if 语句稍有改动：

 print("Welcome to your phones Troubleshooter")
 issue = input(str("Does your phone have an issue?"))
 if issue == "yes" or issue == "Yes" or issue == "YES":
      print("There is an issue")

您应该阅读 if 语句语法。你做错了。

Answer 2

print("Welcome to your phones Troubleshooter")
issue = input(str("Does your phone have an issue?"))
accepted_string = {"yes", "Yes", "YES"}
if issue in accepted_string:
  print("Found it")
else:
  print("Not found")
